MV Grey Lady is a high speed catamaran ferry operated by Hy-Line Cruises that travels on a route between Hyannis and Nantucket.
The vessel was designed by Incat Crowther and ordered from Gladding-Hearn Shipbuilding in February 2002. [1] While she was originally to be named Grey Lady III, following two previous ferries of that name, [1] when she was delivered in May 2003 she bore the name Grey Lady. [2] She is the third Incat ferry to be operated by Hy-Line, preceded by Grey Lady II (now Lady Martha) and succeeded by Grey Lady IV. [3]
Grey Lady is 144 feet (44 m) long, with a beam of 35 feet (11 m) and a draft of 6.5 feet (2.0 m). [1] She displaces 142 Long Tons and is 86 Gross Tons. Her speed comes from four KTA50M2 Cummins diesel engines spinning four Hamilton water jets through Reinjtes gearboxes. [4] The engines can propel her at up to 38 knots (44 mph), though her normal service speed is 31 knots (36 mph). [1] She has a passenger capacity of 300. [1]
